Rush Hour

How Rush Hour works

In short: Slide the cars and trucks out of the way to drive the red car to the exit. The play area is a 6 by 6 grid gridlocked with cars and trucks, it is rated a sliding logic jam, and every jam is solvable - reset and retry as often as you like.

Key facts about Rush Hour

Learn Rush Hour in five steps

The goal

Slide the red car along its row and out through the exit on the edge of the board. The puzzle is won the instant the red car leaves the grid.

Moving a vehicle

Drag a car or truck forwards or backwards along the lane it is parked in. Vehicles never turn, so a horizontal one only slides left and right, and a vertical one only up and down.

Clearing the way

Each vehicle can only move into empty cells, so freeing the red car's row usually means shifting several others out of it first, in the right sequence.

Trucks and cars

Cars take up two cells and trucks take up three, so trucks are harder to tuck out of the way and often decide how tight the whole jam really is.

Winning

Get the red car to the exit to solve the jam. Every puzzle has a solution, so if you paint yourself into a corner you can reset and try a different order.

Where Rush Hour came from

Rush Hour was invented in the 1970s by Nob Yoshigahara, a celebrated Japanese puzzle designer known for his inventive mechanical puzzles. He built the sliding-traffic idea into a compact grid where one special car has to escape a jam of blocking vehicles.

The puzzle reached a global market in 1996, when the American company Binary Arts, later renamed ThinkFun, began producing it with numbered challenge cards ranging from beginner to expert. That graded set of set-up cards, each a separate puzzle on the same board, was a large part of its success.

Rush Hour went on to sell many millions of copies and win a place in puzzle collections worldwide. It has also drawn attention from mathematicians and computer scientists, who study sliding-block traffic puzzles like it as examples of surprisingly hard planning problems.

Tips to solve Rush Hour faster

💡 Best move: Best move: find the vehicles directly blocking the red car's row first, and work out where each one must go before you touch anything else.

1. Solve backwards from the exit by asking what has to move for the red car to reach the edge, then what has to move to allow that, and so on down the chain.
2. Respect the lanes, because a blocker can only slide along its own row or column, so check it actually has an empty cell to move into before you count on shifting it.
3. Give the long trucks priority, since a three-cell truck needs a lot of clear space and often has only one place it can go, so build the rest of your plan around it.
4. Avoid shuffling vehicles at random, because every move that does not help clear the red car's path is likely to clog a lane you will need later.
5. When a jam feels impossible, look for the one vehicle everything else is waiting on, move it first, and the rest of the tangle usually loosens.

Sharper tactics for Rush Hour

1. Trace the dependency chain. Blocker A cannot move until B shifts, and B cannot shift until C does, so reading that chain to its end reveals the true first move, which is rarely the car nearest the exit.
2. Count empty cells like a budget. With so little free space, every move either opens a lane you need or wastes room you will miss later, so spend those gaps deliberately.
3. Watch for mutual blocks, where two vehicles each sit in the only space the other needs. Spotting these standoffs early tells you which one must take a detour through a third lane.
4. The long trucks are the skeleton of the jam. Because they need three clear cells and can seldom move far, planning their few possible positions first constrains everything else into place.
5. If a straightforward plan stalls, look for a move that seems to go the wrong way, since freeing the exit often requires first sliding a vehicle deeper into the board to open the lane another one needs.

Mistakes that trip people up

• Sliding cars at random - find the vehicles blocking the red car first and work out where each must go before you move anything.
• Forgetting vehicles stay in their lane - a car only slides along its own row or column, so check it has an empty cell before counting on it.
• Leaving the long trucks for last - a three-cell truck needs lots of space and has few options, so plan the jam around it first.
• Only ever pushing toward the exit - sometimes you must slide a vehicle deeper into the board to open the lane another one needs.

Ways to play Rush Hour

Classic 6 by 6

The standard board where cars, trucks and one red escapee are packed into a thirty-six cell grid with a single exit to reach.

Graded challenge cards

The traditional set-up decks that fix the starting jam, ranging from gentle beginner boards to expert tangles with long solutions.

Bigger boards and extra exits

Larger grids or added exits that raise the piece count and open new escape routes, deepening the planning required.

Themed traffic jams

Versions that reskin the vehicles as trains, boats or spaceships while keeping the exact slide-only-in-your-lane rule intact.
